Surface rehabilitation of Portland cement concrete (PCC) pavements using single or double surface dressings with soft bitumen, conventional or modified emulsions

Surface dressings are a sustainable maintenance alternative for pavements with surface distresses, due to the low amount of resources involved. This paper aims analyze viability using twelve different dressing solutions, including three binders (conventional and modified emulsions, soft 160/220 bitumen) covering diluted emulsion, treatment Portland cement concrete (PCC) pavements. Several test methods were used evaluate macrotexture, skid resistance, adhesion, resistance wearing on large scale prototype. In general, single increased further macrotexture pavement surface. The double was similar. best in pull-off that bitumen. conventional emulsions presented similar mechanical adhesion Vialit plate test. Concerning prototype test, result obtained bitumen covered emulsion. Based this work’s results, potential rehabilitation
